ABSTRACT:
An improved method for flocculating suspended particulate solids from an acidic aqueous medium and for clarifying said aqueous medium comprises initially contacting the suspension with a water-soluble polymer having an anionic character followed by contacting the suspension with a water-soluble polymer having a cationic character. Such method is particularly useful in clarifying acidic aqueous media used in mining operations, etc.
